General Description

The PDU138-series device is a 3-bit digitally programmable delay line.

The delay, TDA, from the input pin (IN) to the output pin (OUT) depends on the address code (A2-A0) according to the following formula: TDA = TD0 + TINC * A PIN DESCRIPTIONS IN OUT A2 A1 A0 EN/ VCC GND Delay Line Input Non-inverted Output Address Bit 2 Address Bit 1 Address Bit 0 Output Enable +5 Volts Ground where A is the address code, TINC is the incremental delay of the device, and TD0 is the inherent delay of the device.

The incremental delay is specified by the dash number of the device and can range from 0.5ns through 50ns, inclusively.

Key Features

  • Digitally programmable in 8 delay steps Monotonic delay-versus-address variation Precise and stable delays Input & outputs fully TTL interfaced & buffered 2 10 T L fan-out capability Fits standard 16-pin DIP socket Auto-insertable N/C N/C N/C IN OUT N/C EN/ GND data 3 ® delay devices, inc.
